OVEN FOR COOKING-STOVES AND FURNACES.

Specification of Letters Patent.

Patented Nov. 5, 1912.

Application filed April 4, 1912. Serial No. 688,481.

To all whom it may concern:

Be it known that I, WILLIAM A. SCOTT, a citizen of the United States,residing at Ocala, in the county of Marion and State of Florida, haveinvented new and useful I1nprovements in Ovens for Cooking-Stoves andFurnaces, of which the following is a specification.

This invention relates to improvements in cooking stoves and furnacesand especially with reference to the ovens thereof, the object of myinvention being to provide improved devices connected to and carried byand movable with an oven door, whereby bread or other material to bebaked may be put into and taken out of the oven by simply closing andopening the oven door and may, when in the oven, be turned as may berequired to cause it to bake evenly at all times thus entirely relievingthe cook of the necessity of placing his hands in the oven either forputting in or taking out the articles in the oven, the inventionconsisting in the construction, combination and arrangement of deviceshereinafter described and claimed.

In the accompanying drawing ;Figure 1 is a vertical sectional view of aportion of the oven of an ordinary cook stove provided with my improvedbaking devices. Fig. 2 is a horizontal sectional view of the same on theplane indicated by the line 22 of F ig. 1. Fig. 8 is a detail elevationof a portion of the oven door, showing the latch therefor.

For the purposes of this specification, there is shown in Figs. 1 and 2of the draw ing, a portion of the oven A of an ordinary cook stove, thedoor being indicated at B and this door being, as is usual, hinged atone side as at C so that it may bereadily opened and closed.

In accordance with my invention, I provide a bracket or support 1 whichprojects from the inner side of the oven door at a point slightly abovethe bottom of the oven so that when the door is opened the support- 1 istaken out of the oven and when the door is closed the said support isarranged in the oven and immediately above the bottom thereof. Thissupport may be of any suitable construction and is here shown as securedto the oven door as at 2. On the upper side of the support is a lowercarrier 3. This carrier is circular in form and is arrangedfor rotationon the support and in the oven. The carrier is provided withperipherally beveled cogs 4 which extend upwardly from and around thebottom of the carrier so that in effect the carrier forms a pan orplatform on which a baking pan may be placed or on which articles to bebaked may be directly placed when it is not desired or necessary toemploy a baking pan. WVithin the scope of my invention, any suitablemeans may be employed for mounting this carrier. For the purposes ofthis specification, I show the carrier as provided with a centrallyarranged pivot axis 5 which, in practice, may be a bolt which extendsthrough a central stud 6 that projects from the lower side of therevoluble carrier. This stud is here shown as mounted in a bearing 7with which the support is provided, the said stud being countersunk inthe bearing and I also show a nut 8 screwed to the lower end of the boltand arranged in a countersink in the lower side of the support so thatthe lower ends of the bolt and nut are flush with the lower side of thesupport and do not interfere with the movement of the device in and outof the oven when the door is opened and closed. The revoluble carrier 1with which the oven door is provided. On"

the inner end of this shaft and arranged on the inner side of the ovendoor is a beveled pinion 13 which engages the beveled gear of therevoluble carrier. This pinion may be secured on the shaft in anysuitable manner and by any suitable means. It is here shown as securedby a nut 14, the shaft beingshown as provided with a cross sectionallyrectangular stud 15 which fits in a correspondingly shaped centralopening in the pinion. The outer end portion of the shaft is shown asreduced in diameter and having a threaded portion 16 which is engaged bya nut 17 that bears against the outer side of the bearing 12 so that theshaft is held in place by the nut and also by the hub of the pinion. Tothe outer end of the shaft is secured asuitable crank 18 which has ahandle 19 whereby the shaft may be rotated from the outer side of theoven door so as to cause the pinion 13 to rot-ate the revoluble carrierwhich is within the oven when the door is closed. Hence, the carrier maybe turned as may be required to prevent bread or other articles fromburning and to cause the same to bake evenly at all points, and this maybe done without the necessity of opening the door and also without thenecessity of the cook placing his hand in the oven.

A supporting bracket 20 is arranged at a suitable height above thecarrier 3 and is here shown as secured to the inner side of the ovendoor as at 21. This supporting bracket has an opening 22 through whichthe upper side of the pinion 13 extends and is substantially identicalin construction with the support 1, being provided at points 90 apart onits upper side, with recesses 23 in which bearing balls 24 are placed.An upper carrier 25 which is substantially identieal in constructionwith the lower carrier 3, but which has its beveled cogs 26 on its underside and engaged with the upper side of the pinion is mounted forrotation on the supporting bracket, being provided in its under sidewith a circular groove 27 which is engaged by the bearing balls 24. Onthe under side of the upper carrier at the center thereof is a stud 28which is countersunk in a bearing 29 with which the supporting bracket20 is provided, the pivot or axis of the upper carrier being here shownas formed by a bolt which extends through a central opening in the uppercarrier and the bearing, has its head countersunk in the bottom of thecarrier and is provided at its lower end with a nut 31 which I iscountersunk in the lower side of the bear forms in effect a pan orplatform on which a baking pan may be placed or on which articles to bebaked may be directly placed when it is not desired or necessary toemploy a baking pan and by the provision of the upper carrier as well asthe lower carrier it will be noted that bread or the like may be bakedeither in the lower or upper portion of the oven.

To enable the cook to ascertain the condition of the article or articlesbaking in the oven, the door is provided with an opening 32, one ormore, at any suitable point which opening is covered by a pane of glassor other transparent material 33, the glass pane being held in a groove3 1 in a frame 35 and between asbestos strips 36 so that the glass isprotected from excessive heat and from being detachably secured in theoven door by means of bolts 37.

In order to secure the door in closed position, I provide the door witha pivot catch 38. The pivot axis of this catch is extended on the outerside of the door and is provided with a suitable handle 39 whereby thecatch may be raised and lowered. This catch engages a keeper 40 on oneside of the door frame and when the door is open is prevented fromdropping too far by means of a stop stud 4C1 which projects from theouter side of the door.

It will be understood that it is not necessary to raise the oven doorbefore opening it and all that is required is to partly turn the catchso as to cause the catch to rise a sufficient distance to becomedisengaged from the keeper.

While I have herein shown and described a preferred form of myinvention, I would have it understood that changes may be made in theform, proportion and construction of the several parts without departingfrom the spirit of my invention and within the scope of the appendedclaims.

I claim 1. An oven door having a support extending from its inner side,a revoluble carrier mounted on the support and having a gear, and ashaft mounted in the door and having a gear at its inner end engagingthe gear of the carrier, the said shaft being provided at its outer end,on the outer side of the door with means whereby said shaft may beturned to cause the carrier to be revolved.

2. An oven having a door provided on its inner side with a lower supportand an upper support, a revoluble carrier mounted on each of thesupports, and means carried by the door to revolve the said upper andlower carriers.

3. An oven door having a lower support extending from its inner side, alower revoluble carrier mounted on the lower support and having a gear,an upper support also extending from the inner side of the door, anupper revoluble carrier mounted on the upper support and having a gear,and a shaft mounted in the door and having a gear at its inner endengaging the gears of the carriers, the said shaft being provided at itsouter end on the outer side of the door With means whereby said shaftmay be turned to cause the carriers to be revolved.

In testimony whereof I aflix my signature in presence of tWo Witnesses.
